Custom GPT stopped working

Hi,

I have a Plus account and I am testing custom GPT functionalities like action calling with custom API. Everything was fine until yesterday when I started to receive the following responses in ChatGPT.​

> [debug] Calling HTTP endpoint
< [debug] Response received
Error talking to domain

I am 100% sure everything is OK on my test server, there are no firewall restrictions, SSL cert is fine, no robots.txt and so on. Worked well until yesterday. I can reach the server from different locations and the API calls return proper data… What I can’t see is the ChatGPT calling my server - the http server logs are empty.

Anyone experienced such an issue?

ChatGPT doesn’t give any reasonable clues on this issue.

Regards,

Michal

That happened to my custom gpts as well… you can just create a new one by copy pasting everything to the new one and it should work… at least that worked for me… I am now on version 4 (autocoder → autocoder2 → autocoder3 → autocoder4) was my naming strategy
